WOOD, OF BROOKLYN, NEW YORK.

ARTIFICIAL SHINGLE.

Application filed June 7, 1923. Serial No. 643,902.

To all whom it may concern:

Be it known that I, CHARLES H. HARRIS,

a citizen ofthe United States, residing at.

Cranston, in the county of Providence and State of Rhode Island, have invented'certain new and useful Improvements in Artificial Shingles, of which the following is a specification.

The objects of my invention are,first,

to provide a means to secure or look the lowermost edge of the shingle to the roof to prevent it curling up or warping, and second, to provide a starting strip which will act as a gauge along the-eaves and enable the workman to apply the shingles accurately and rapidly.

These objects are attained by my shingle and starting strip illustrated in the accompanying drawings in which Fig. 1 is a plan view of a portion of a roof u on which the said invention has been applled; Fig. 2 is an enlarged rear or bottom view of one of I my shingles; Fig. 3 is an enlarged rear or bottom view of the starting strip; Fig. 4 is a still larger plan view of a ortion of a roof upon which some of the s ingles have been applied, and Fig. 5 is a sectional detail on the line 55 of Fig. 3.

Like reference characters refer to like parts in the several figures.

Referring now to the drawings, the shingle, 10, is made, preferably square, of any desirable material, and of a size to provide convenience in manufacturing and application as well as a neat appearance when applied to the roof. Each corner'of the shingle has a ail hole, 11, equidistant from the sides whi-e one corner, 12, as for example the lowermost corner, is folded back flat against the under side, forming a close crease 13, which is perpendicular to the vertical diagonal of the square.

The starting strip, 14, is of the same thickness as the shingle, is made of the same material, and is in length preferably a trifle less than twice the diagonal length of the square shingle, 10. 'A portion, 15', is folded back forming a crease 16, and a hole, 17,

passes through the two thicknesses of the starting strip, 14, midway of the length and the same distance from the crease, 16, as the hole, 11, in the corner, 12, of the'shingle, 10, is from the crease 13.

In applying the shingles the starting strips are attached in the following manner: The corner, 12, of one of the shingles 10, is opened out and a flat headed nail, 11', of the type commonly used for attaching artificial shingles is driven through the hole, 11, and the hole, 17, in the starting strip, 14, into the roof, 18, so that the crease, 16, of the starting strip comes fiush with the eaves or lowermost edge of the roof. The shingle is then pushed or dropped back flat against the roof, covering the nail in the corner, 12, and nails, 11', are then driven through the other three holes, 11, securing the starting strip as well as the shingle to the roof. Then another starting strip is attached in the same way leaving a clearance between the abutting ends'of the two starting strips equal to the diameter of a nail and so on all along the eaves. Then a shingle is attached at the juncture of every two starting strips, the nail through its corner, 12, being driven between the strips as shown in the drawings.

It is customary in order to give the roof a solid appearanceto have a double thickness ofshingles at the eaves and this is accomplished by the fold in the starting strip as above described.

It will be noted that the first row of shingles may be easily alin'ed by causing the corners to meet as shown in Fig. 4.

The second row of shingles is then easily attached and alined by fitting the folded parts beneath it there can be no openin or crevasses left through which rain, win or snow can creep.

It will be noted that irrespective of the form of the upper half of a shingle, its lower 'half preferably takes the form of aright isosceles triangle whose angular corner is folded under and flatly creased horizontally. and parallel to the diagonal passing throu the side corners of the shingle, whereby said folded under corner fits flatly and precisely into the right angular space formed by or between the adjacent side corners of the two shingles over whichthe shingle having the folded under corners is placed, as clearly shown in Fig. 4 in one portion of which is indicated how the fastening nail is driven through the folded under corner, 12, while having predetermined holes in the four corner portions thereof, said holes being spaced uniformly from the edges of said shingles, one corner of each. of said shingles being folded under forming a fiat crease parallel to a diagonal of the shingle and equidistant therefrom in the several shingles, a fastener adapted to pass through the hole of said folded under portion so that the head thereof will be covered by the main portion of the shingle, and a series of starting strips of uniform dimensions spaced from each other to allow the passage therebetween of one of said fasteners, each strip having a predetermined hole formed therethrough of uniform location with respect to the ends and bottom edge thereof for co-operation with the corresponding hole in the folded under corner of a shingle.

2. In shingle roofing, a plurality of like shingles the lower portion of each of which is of right isosceles triangular form and having its corner folded under and creased along a horizontal line per endicular to the vertical diagonal constituting a bisector of the right angular .corner, said folded under corner having a hole formed therethrough, and a series of starting strips, each of a length substantially equal to a multiple of the horizontal diagonal of the shingles and of a width greater than the aforesaid triangular portion of a shingle, the lower edge portion of the starting stri being straig t and unbroken and provide with a hole in its center as far from its lower edge as the hole aforesaid in the folded under corner is A spaced from the crease.

3. In shingle roofing, a plurality of shingles each having an isosceles triangular lower portion, the lower point of which is folded back and under the main portion around a folding line horizontal and parallel to the diagonal passing through the side corners of the shingle,

said folded under point having a hole formed therethrough at a predetermined distance from the folding line, said fold ed under point being shaped to fit directly into the angular space between the abutting side corners of the two shingles 1 covered by the shingle having the folded under point, and a series of starting strips for application adjacent to the eaves, each strip having a hole formed therethrough and spaced from its lower edge substantially the same distance assaid shingle point hole is spaced from the folding linein the shingle, said hole in the starting strip being spaced from one end ofthe starting strip a distance substantially equal to the diagonal length of the shingle between its slde corners, and a fastener adapted to pass through the foldedunder oint of a shingle and said starting strip ho e and be covered and hidden by the main portion of the shingle.

In testimony whereof I aflix' my s gnature.
